How Can I Get Better Positional Accuracy?
The wide area augmentation systems only improve the positional accuracy by a small amount. To get a significant improvement in positional accuracy, you will need to set up your own local Base Station. A local Base Station is a portable unit that will transmit local DGPS corrections via radio over short distances. There are currently three levels of accuracy improvement available with VBOX products when using a Base Station:
- 40 cm RTCM available to all VBOXII and VBOXIII products.
- 20 cm proprietary correction only available to upgraded VBOXIIS and VBOXIISX units.
- 2 cm RTK proprietary correction only available on RTK enabled VBOX3i, VBOX 3iS and VBOX Touch units.
